To all whom it may concern Be it known that EDGAR L. Lone, a citizen ofthe United States, residing at Baltimore, State of Maryland, hasinvented certain new and useful Im rovements in Lubricating Systems forwhich the following is a specification.

This invention relates to new and useful improvements in lubricatingsystems for railway cars, and more particularly to a means forlubricating the journal boxes on the trucks of said cars.

The principal object of the present invention is'to provide alubricating system of the above mentioned character, wherein the oil iscontinuously circulating through the journal boxes while the car isin'motion,

thereby obviating the necessity of employing waste or other absorbentmaterial in the journal boxes to hold the lubricant.

Another important object of the present invention is to provide alubricating system of the above mentioned character, whichineludesa-coolin means whereby the oil dur ing the circulation thereofthrough the journal boxes will at predetermined times be cooled, thusinsuring-the proper lubrication of the journal boxes and preventing theoverheating of the same.

A further object of the present invention is to provide a lubricatingsystem of the above mentioned characterwhich is adapted to be mounted onthe truck of a railway car and operatively connected with the axles ofthe wheels on the-truckwhereby the pump forming a part of thelubricating system will be caused to operate simultaneously with themovement of the axles, thereby assuring a continuous circul'ationof thelubricating medium to the journal boxeswhile the car is in motion, meansbeing associated with the pump for preventing the accidental return ofthe lubricating medium during the delivery thereof to the jourfialboxes.

Another important object of the invention is to provide a lubricatingsystem of the above mentioned character wherein means is ass ciated withthe truck'of a car for sup porting the pump in an operative ppsitionthereon, thus permitting the device to be rcadilyand easily accessible.

A still further object of the invention is to provide a lubricatingsystem of the above mentioned character, which is simple in conailwayCars, of

struction, inexpensive, strong and durable, and further well adapted forthe purposes for which it is designated.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawings forming a part of this specification, andin which like numerals designate like parts throughout the same,-

Figure 1 is a side elevation of a truck of a railway car showing myinvention in posh Figure 6 is a sectional view of the pump 3 showing thevalves therein;

Figure 7 is a detail perspectiveiview-of the pump supporting bracket.

, In the drawings wherein for the purpose ofillustratiou is shown thepreferred embodiment of my invention, the letter A designates generallythe truck of a. railway car, the same comprising the axles B, the latterhaving theusual wheels 0 mounted on the outer ends thereof in the wellknown manner. The bolster is designated by the letter D and as the sameis of the usual construction, it is not thought necessary to fur therdescribe the detailed construction of the i same; Carried by the axles Bon the outer ends thereof are the journal boxes E. As each journal boxis of thesame construction it is thought that the description of onewill 7 suilice for the description of all.

The journal box is provided in its upper I portion with the verticallyextending passage 1 and this passage is adapted to com municate with asimilar passage 2 provided 1n the bearing 3 which extends partly aroundthe reduced portion of the axle B.

'lheglovver portion of thejournal box pro forreceiving the oil or otherlubricating mevideb what I term as a reservoir and is desgnated' by thenumeral 4111 the drawings diu'm which has been delivered to the axle Bin the manner as will be presently described.

Secured to the lower portion of the bolster D is-the bracket 5, thelatter having formed at one end thereof the arcuate channel member G,the construction of which is clearly illustrated in Fig. 7 of thedrawings. This bracket is adapted to we supported by the bolster. I) inthe manner as clearly illustrated in Fig. 3 of the drawings, and thepurpose thereof is to provide a means for supporting the pump designatedby the numeral '7. This pump comprises the coinplementary sections 8 and9, respectively, and these sections have their flanged por tions securedtogether by any suitable tastening means such as is shown at 10 in thedrawings.

The channel portion (5 of the bracket 5 when in position on the bolsterD will be adapted to receive the flanged portions of the bottom of thepump whereby the latter will be supported in a substantially rigidposition on the truck and to further hold the pump in position on thetruck, I have pro vided additional supporting brackets desig nated bythe numeral 11. Extending transversely through the section 8 of the pump7 is the shaft 12 and the outer end thereof is adapted to be supportedin the bracket 11 as is clearly shown in Fig. .3 of the drawings, theinner end of the shaft supporting the pump rotor 13. Carried by theouter end at the shaft 12 is the gear wheel 14: and this gear wheel isadapted to mesh with a similar gear wheel 15 which is mounted on theaxle B, it being understood that the gear wheel 15 is of such aconstruction as to, permit the same to be readily placed around the axleand to this end I have constructed the gear wheel 15 of two like partsor sections, the same being locked together on the axle B by means ofthe fastening means shown at 16 in the drawings. The purpose ofproviding the gearing arrangement is to provide a. means whereby thepump rotor 13 will be simultaneously rotated with the operation of therailway car upon which the truck A is associated and in which the axle13 rotates.

Communicating with the section 9 of the pump 7 adjacent the pump member13 therein is the pipe 17, the latter extending outwardly from thesection 9 for a suitable distance and communicating with a shortsection. of pipe 18 such as is clearly illustrated in Fig. of thedrawings. The pipes 17 and 18 are termed what I call suction pipes. The

.outer end of the pipe l8-is connected by a suitable coupling or nippleto the elongated sections of pipes 19 and 20, respectively. The outerends of the pipes 19 and 20 communicate with the bottom portions of thejournal boxes E mounted on the opposite ends of the axles B, as is alsoclearly illustrated in Fig. 4 of the drawings. The purto I recesses poseof this arrangement will be more fully described later.

As is clearly illustrated in the drawings in Fig. 3 particularly, itwill be seen that the shaft 12 and the pump rotor 13 supported on theinner end thereof in the sections 8 and 9, is disposed in a plane belowthe axle 15, whereby the operation oi the pump will at all timesbepositive and will furthermore create the proper suction therein forcausing the circulation of the lubricating medzum tl'ierethrough. Thesection of piping 17 is adapted to be supported in the outer end of thebracket 11 which is mounted on the bolster .l) to assist in supportingthe pump in an operative position on the truck.

Extending from the upper portion of the pump casing 7 is the outlet pipeThis pipe 2]. is connected by any suitable means to the coil pipe whichextends substan tially in a horizontal plane above the pump and in orderthat the coil may be held in a horizontal plane. I provide thesupporting racket-s shown at 23 in Fig. 5 of the drawings. Thesesupporting brackets are supported on the bolster D and have their outerfree ends adapted to receive the coiled portions of the pipe 22 in themanner as is clearly illustrated in Fig. 5 of the drawings 1 The purposeof providing the coil sections iii) 22 is to provide what 1 term as :1cooling' means for my lubricating system.

The outlet end of the coil pipe 22 communicates with the pipes 24; and25, which are connected thereto by means of a suitable connection shownat 26 in the drawings, and these pipes and extend longitudinally withrespect to the axles l3 and coinmunicatc with the transversely extendingpipe 27, which is disposed between the journal boxes E on both sic s ofthe wheels (1, in the manner as clearly illustrated in Fig. 2 of thedrawings, and the pipe 27 has its outer ends communicating with theupper portions of the inlet pipes 28. These inlet pipes are in turnsupported in the upper portions of the journal boxes and adapted tocommunicate with the inlet passage 1.

A valve 29 is located in the coilpipe Q2 adjacent the outlet end thereoffor the purtion with the bottom of each journal box IE,

in the manner as clearly shown. in Fig. of

. opened and the valve 32 in the by-passv" ip'e 31 is closed. Withthe'parts arranged the drawings, whereby a complete circulating systemis rovided between the journal boxesEandt epump 7.- v

The operation of m lubricating system may be briefly descri ed asfollowsz-In the summer time, the valves'30 and '29' are let pipes 18 and17 and finally into the pump casing 7 Where the pump rotor 13 will forcethe same through one of the passages therein, and past either of thevalves 34shown in- Fig. 6 of the drawings, and depending upon thedirection in which the car is travell ng,

up through the outlet pipe 21. I' 'he oil passing through the outletpipe 21 will lie-"delivered through the roiled portions 22 where thesame will be permitted to expand and then through the pipes 27 intotheupper portions of the journalboxes, where the 011 will be finallythrough the passages 1 and .2, 'ontoifthe axles B, thus prov'iding for acontinuous.- circulation of the lubricating oil and obviating thenecessity of having to employ waste or other absorb- 1 out material asis now commonly used and placed in the bottoms of the journal boxes tohold the lubricant therein.

In the winter time the cooling of the lubricating oil by havingthesameass throu h the cooled portions 22 may be lminated by closing the valves29 and 30 and opening the valve 32, whereby the oil will be caused, 'topass from the pump through the outlet pipe 21 into the by-pass pipe 31and be delivered-to the journalv boxes, in the manner as heretoforedescribed. However, the circulation of the oil through the by-pass pipewill also provide for the continuous c 1r-' culation thereof 1n the samemanner as when" thecoiled portions are in use.

Itwill thus be seen from the foregoing description that a lubricatingsystem for a railway car hasbeen provided wherein the journalboxes willbe continuously lubricated during the movement of the car andfurthermore a constant circulation of the lubricating medium vwill beobtained. The facility with which my device is, placed in position uponthe truck of a railway car will enable the body a person-to have'readyaccess thereto whenever it is neeessa to repair or control any of theparts or va ves, thereof and it will not require the alteration oraddition of arts to lubricatlng system in'position on the truck. Fromthe foregoing description of the con-' struction of in improvedapparatus, it will; be seen that I ave provided a simple, inexpensiveand eflicient means for carrying out the objects of the invention, andwhile I have particularly described the elements best adapted to performthe functions set forth,

of the car in order to p ce my it is obvious that various'changes inform, proportion, and in the minor detailsof construction may beresorted to,' without de-' parting-"from the spirit or sacrificing anyof the principles of the invention.

Having thus described my invention, what I- claim as new and desire tosecure by Letters Patent is:- p

1. The combination with the truck of a car including the axles and thejournal boxes therefor; of a lubricating system associated therewithcomprising'a pump, ashaft extending transversel through said pump, a
